Name of variety in France (and usual designation)
Berlandieri - Colombard 2 (BC 2)
Breeder/selector and year of obtention
Mr Blanchard and Jean-Louis Vidal, 1894.
Genetic origin

Descriptive elements
The identification is based on:
- the tip of the young shoot that is open, with a high density of prostrate hairs and a piping anthocyanin coloration,
- the bronzed young leaves,
- the shoots with a very ribbed surface,
- the medium to large, wedge-shaped adult leaves, with a fairly thick leaf blade, shallow upper lateral sinuses, a slightly open lyre-shaped petiole sinus, long teeth compared to their width with straight or convex sides, and a low to medium density of erect hairs on petioles and on the veins on the lower side of the leaves,
- the hermaphrodite flowers,
- the small, round-shaped berries with a blue black skin.
